This invention relates to fasteners of the stud and socket type, and has particular reference to socket elements adapted to be rig'- idly mounted in articles or supports such as the door boards of automobiles, whereby the l'oor mats or carpets which carry the complemental stud elements may be attached.

The object of the invention is to provide a socket elementv ofthe character referred to which may be easily and cheaply manufacL tured by means of automatic machinery, and which lends itself readily to assembly with its support.

The invention consists in a socket element having a barrel and a flange and means for securing it to its support, the barrel being provided with a constricted portion adjacent to the iiange for engagement with a complemental stud element, all as will be described 2 hereinafter more fully and finally claimed.

` In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view, Fig. 2 is a bottom plan view, and Fig. 3 is a side view of the finished socket element. Figs. 4, 5 and 6 are axial sections illustrating threesteps contemplated by the method of manufacturing the socket elements, Fi 6 being a section on line 6-6 of Fig. 2. igs. 7 and 8 are sectional elevations showing the manner in which the socket elements may be assembled with their supports, and' Fig. 7 shows, in broken lines, a

complemental stud element.

In making the socket elements of the invention a blank is formed to cup shape, as illustrated in Fig.,4, provided with an outwardly extending flange 1 and a barrel 2, the barrel having a closed end 3. The' closed end 3 is then pierced by means of a suitable tool to produce attaching means preferably in the form of a plurality of radially outwardly extending prongs 4. Then the barrel 2 is knurled or rolled adj aoent tothe flange 1 to produce a peripheral impression 5 forming a constricted portion in the barrel with which the head 6 of a stud 7 may engage with a snap action (see broken lines Fig. 7). All ofthese operations may be performed as sequential steps in the Operation of an auto matic machine', thus making the manufacture of these socket elements very simple and Inexpensive.

It is to be noted that in the piercing of the l en d 3 of the barrel 2 the spreading of the prongs 4 is so controlled that their outstanding points lie within the diameter of the barrc1 (see particularly Fig. 2) and that the curvature of the barrel 2 adjacent to the prongs 4 is such that the lower portion of the barrel is of less diameter than throughout the major portion of its length, both for purposes hereinafter explained.

As shown in Figs. 7 and 8, the support or article 8 with which the socket elements are assembled, such as the licor board of an automobile, is provided with a bore 9 for each socket element to be used, these bores so located as to most advantageously attach the mat or carpet to be secured.

As will be seen, the bore 9 is of such diameter as to closely fit the barrel 2 of the socket element, and the prongs 4 lying within the diameter of the barrel 2 will be encompassed by the bore in such a manner that the socket element may be readily slipped into the bore, as shown in Fig. 7, the iange 1 limiting insertion by Contact with the face of the support. v

With the socket element thus positioned an appropriate tool 10 having a suitably tapered end-11 is inserted in the barrel and struck with a hammer` or other implement. The

`force thus applied will drive the tapered end 11 of the tool past the reduced diameter portion of the barrel 2 adjacent to the prongs and acting thereagainst will force the prongs radially outwardly and into the support, as shown in Fig. 8, the shoulder 12 of the tool finally limiting inward movement of the tool by contact with the iiange 1 and forcing the flange into close and intimate engagement with the upper surface ofthe support. The tool 10 is thereafter withdrawn and the socket element thus rigidly -attached to or assembled with the support is ready for reception of its complemental stud element.

Various changes and modifications are considered to be within the spirit of the invention andthe scope of the following claim.

What I claim is A socket element for separable fasteners, comprising a tubular barrel provided at one end with an outwardly extending flange and at its other end with outwardly extending -prongs whereby it may be attached to an article, said ron normally lying within Athe l diameter o the arrel and deformable out of normal position into engagement with said l0 article, said barrel provided with a constricted portion ad'acent to said flange and v forming a means or separable engagement .with a complemental stud element.

In testimonywhereof I have hereunto set my hand.
